255/30 and decent offsets u will c no rubbing. but if u go a bit more aggressive u will have some rubbing on the insider part of th wheel well, the plastic part. I noticed that with my 360's when i put a small spacer to go as aggressive as possible. But with normal (somewhat conservative) offsets u will notice 0 rubbing. For my next set I think Im going as aggressive as possible therefore rolling with a 245/30. hope this helps as well.
